conversion of myopia degree

The eye may show decreased vision due to eating color. However, there is a disproportionate relationship between the degree of myopia and uncorrected vision. In addition to strength test, there are many reasons for decreased vision, such as cataract fundus disease, reflection and hyperopia. Under normal circumstances, myopia and astigmatism can coexist. Both can cause decreased vision. In addition, everyone's eye accommodation ability is different, and even the same uncorrected vision can be different. It is recommended that after showing a decline in vision, you need to go to the hospital in time for optometry and fundus examination to clarify the cause, and to clarify the specific myopic degree through optometry.
